To all lwhom t may concern.'

Be it known that I, CLINTON C. MURPHY, a citizen of the United States,and 4a resident of the city of Chica-go, inA the county of Cook andState of illinois, have invented anew and useful Improvement in Car-Roofs, of which the following is a specifica-h tion.

This invention relates to outside metal roofs for railway cars, and theobjects of the invention are to improve the ridge eonstruc- 'tionthereof and the joints or seams between the roof sheets.

rThe invention consists in the form and arrangement of the metal sheetsand fastencharacters are used to designate like parts in the severalviews, Figure 1 is a plan view of the end portion of a car roofembodying the invention, parts of the roof being removed to disclose theunderlying construction; Fig. 2 is a vertical cross-section through theroof on the line 2 2 in Fig. 1,

drawn to a somewhat larger scale than Fig. 1; Figs. 3 and 6 are verticalcross-sections of the ridge portion of the roof on the lines 3 3 and 66, respectively, in Fig. 1, the

running board saddle in Fig. 6 beingpartly in elevation; Figs. 4 and 5are vertical crosssections of the eaves of the roof on the lines 4 4 and5 5, respectively, in Fig. 1; Fig. 7 is an end elevation of the ridgeportion of the car roof; Fig. 8 is a longitudinal section of the end oftheridge of the roof, on the line 8 8 in Fig. 1; Figs. 9 and 12 are planviews showing the arrangement o f the ridge corners of the roof sheets,F1g. 9

n showing the arrangement between the ends of the car and Fig. 12 thearrangement at the ends of the car; Figs. 10 and 11 are detail views ofa corner cap, Fig. 10 showing the under face, and Fig. 11 the half sideelevation and half central llongitudinal section; Figs. 13 and 14 arecross-sections of the side and of the ridge seams or Joints between theroof sheets on the line 13 13 and 1& 14 in Fig. 1, respectively; Figs.-15 and 16 are perspective views of a ridge seam cover strip and a sideseam cover strip, respectively; Fig. 17 is a perspective view of an endside seam cover strip; and Fig. 18 is a perspective view of an end ridgeseam cover strip.

In the drawings, the metal roof constituting the invention is shownapplied to a car having roof boards 11 supported at their ends by theside plate 12 and ridge pole 13. End plates 14 connect the side platesat the ends of the car and support the ridge pole. The arrangement ofthe substructure on which the metal car roof is applied is no part ofthe present invention, and may be other than as above described. Themetal roof constituting my invention consists of roof sheets 15. whichare arranged in pairs sheets are ilanged up', the extremities of the.

flanges 16 being turned in and bent down, forming sloping inner walls 17terminating above the margins of the sheets.

The ridge ends of the roof sheets do'not quite touch, and ridge seamcovers 18 of inverted channel shape straddle the end flanges, and haveinturned flanges 19 bent up under the sloping inner walls 17 of the roofsheet flanges, as shown in Fig. 14. The ridge seam covers are somewhatshorter than the width of the roofsheets, and have upturned flanges 20across the ends of their top walls, and outturned flanges 21 at the endsof theirside walls. The side walls are somewhat higher than the roofsheet flanges, and the lower edges of the seam coversrest on the roofsheets, as shown in Fig. 15.

The roof sheets are separated at their sides, and battons 22 are placedcrosswise of the car between the side flanges of the.

roof sheets, the width of the battons being slightly less than the widthof theV spaces between the roof sheet flanges, and the thickness of thebattons being slightly more than the height of the roof sheet flanges.Side seamV` covers 23 of inverted channel shape are arranged over thebattons, the side walls sol 24 of the seam covers resting on the roofsheets inside of their side flanges. The side walls of the seam covershave their lower edges turned in, the turned in portions being bentupward and then downward, forming inverted V-shape flanges 25. The V-shape flanges 25 within the s1de seam covers fit under the sloping innerwalls 17 of the side flanges of the roof sheets, as shown in Fig. 13.The ridge ends of the side seam covers have upturned flanges 26 acrosstheir top walls and the eaves ends have pro]ecting top s 27 which are4adapted to be bent down over the eaves of the car to cover the ends ofthe battens and spaces between their side walls. i

The eaves ends of the roof sheets and side seam covers are loosely helddown upon thesubstructure by means of angle flashing strips 28, andangle clips 29. -(See Figs. 4 and 5.) The angle flashing strlps 28 arearranged lengthwise of the car along the eaves below the ends of theroof sheets, and pass` ing underneath the battens and side seam covers.The inner margins 30 of the flashing strips are folded back over theintermediate portions, and the eaves ends 31 of the roof sheets areturned under and hooked into the turned over inner margins of theHashing strips to form a flexible joint. The outer margins 32 of theflashing strips are bent down over the side of the car, and are fastenedthereto. The angle' clips 29 are outside of the flashing strips, and arebolted to the side of the car below the-eaves.

. The angle clips are spaced away from the ends of the roof sheets andside seam covers and have bent portions projecting'over the eaves andoverlying the roof sheets or side seam covers. roof sheets and side seamcovers from Alifting off the substructure, but do, rigidly in fixedposition.

T he pairs of oppositely disposed roof sheets are loosely pivotedtogether at the middle points of their ridge ends by saddle plates 33.(See Figs. l and 6.) The saddle plates straddle the peak or ridge of theroof. and are provided at their ends with raised bosses 34 of invertedcup shape, which bosses project into mating inverted cup shape bosses 35in the roof sheets. The side walls of the bosses 34 and 35 are slopingand. the angle of slope from the perpendicular is slightly less than theangle ofsliding frictionv between the roof sheet and saddle plate.Positioned above the saddle plates are running board saddles 36, havingtheir under sides shaped to the peak of the roof and provided withrecesses 37 for the roof sheet bosses. The running board saddlesstraddle the ridge seam covers and are fastened to the substructure byvertical bolts 38, which pass through holes in the seam covers.V Theseam covers are anged up around the holes The angle clips prevent the inot clamp "them for-the runningboard saddle bolts 38 to keep water fromfollowing the bolts into the car. The recesses in the running boardsaddles for the roof sheet bosses and the grooves for the ridge seamcovers, are wlder than the parts projecting intoV them in order not tobind the roof sheets.

The ridge corners of the roof sheets, and the ends of the ridge seamcovers and side seam covers, are covered by corner caps 39. The cornercaps are vinverted pan shape, with openings-40 in their end walls toreceive the ridge seam covers, and openings 4l in their side walls toreceive the battens and side seam covers. The corner caps have centerholes which are threaded to fit vertical bolts 42 which secure them tothe substructure. Surrounding the bolt holes -on the unand 26 of theridge seam covers and side seam covers project into the spacesurrounding the flanges 43 within each corner cap.'

These flanges 20 and 26 deflect Water which may follow the tops oftheseam covers under the corner cap off onto the corners of the roofsheets, and thus prevent it from getting into ythe car. Running boardsaddles 44 are arranged over the side seam covers, resting on them andbeing supported by the battens. The running board saddles 44 arerecessed for the corner caps, and the securing'bolts 42 forthe cornercaps go through the running board saddles and hold them down. Runningboards 45, extending lengthwise of the car, are supported on the runningboard saddles and are nailed' or otherwise secui ly fastened thereto.

At the ends of the car ridge" covers 46 and si de seam covers 47.0fspecial form are provided (see Figs. 17 and 18). The outer margins 48 ofthe side seam covers are bent over the end of the car instead of beingflanged to engage the side flange of a roof sheet. The outer end 49 ofthe ridge cover is likewise bent down over the end of the car, coveringthe gap between the ridge ends ofthe downturned margins of the side seamcovers. The sidemargins 52 of the ridge covers 46 are turned down overthe Aend flanges 20 of the seam covers 47. A special to the intermediatecorner caps, except that they have no end walls on the outer ends.

Nails 51, passing through holes' in the outer ends of the end cornercaps, secure the end ridge covers in place.`

From the foregoing description it is evident that the roof sheets arefree to move upon the car substructure in response to distortionsthereobnt are positively located in proper position and held fromslippmg off the eaves by the bosses and saddles. The

Laf-

ridge seam covers are fixed in position by bolts, and assist inmaintaining the alinement of the roof sheets. The ridge and side seamcovers permit movement of the roof sheets, and the form of the interlockbetween them prevents water from entering the car through the seams.
